3 Reasons We Love Branwyn Merino Wool Underwear for Adventure

When it comes to adventure-ready essentials, Branwyn’s merino wool underwear has quickly become one of our go-to staples that we personally love and recommend to our community. Whether we’re hiking through alpine meadows, road tripping across national parks, or flying halfway around the world, the right base layer makes a huge difference. And Branwyn delivers… comfortably, sustainably, and stylishly. We know it can feel a bit pricey up front, but the quality and longevity of Branwyn is well worth it. I just finally retired one of their bralette’s after 4 years of VERY consistent wear.

I can gush about Branwyn for awhile, but here are the three main reasons why I love Branwyn and why their merino innerwear belongs in your travel bag:

1. Merino Wool Magic: Naturally Temperature-Regulating & Odor-Resistant

One of the best parts about Branwyn’s performance innerwear is the natural magic of merino wool. This isn’t the itchy wool you remember from childhood sweaters. It’s soft, breathable, and incredibly smart. Merino fibers help regulate your body temperature, keeping you cool when it’s hot and warm when it’s cold, perfect for multi-climate adventures.

Even better? It’s naturally odor-resistant, which means you can wear it multiple days in a row (hello, packing light!) without worrying about smell. I’ve worn my Branwyn from Havasupai to Kilimanjaro and Branwyn has always kept me feeling fresh.

2. Sustainable, Ethical & Women-Led

We love supporting brands that align with our values, and Branwyn checks every box. Their underwear is made using ethically sourced, ZQ-certified merino wool, which ensures animal welfare, environmental care, and sustainable farming practices.

On top of that, Branwyn is a woman-founded and women-led company, committed to creating products that empower women to feel strong, supported, and confident, no matter where the trail leads.

3. Perfect Fit for Real Life (and Real Bodies)

Let’s be real, when you’re hiking 10 miles a day or sitting on a long-haul flight, the last thing you want is uncomfortable underwear. Branwyn’s designs are seamless, chafe-free, and move with your body. They’re also moisture-wicking, quick-drying, and never ride up. It’s the kind of fit that makes you forget you’re even wearing underwear (in the best way possible). Some women have wondered if the wool is itchy and I’m here to say, it’s not.

From the 7 days Kilimanjaro summit trek to humid hikes in Costa Rica or14 hour flights to our latest adventure, Branwyn’s merino underwear offers the comfort and performance we’ve been searching for.
